Systems and Methods for Using Acoustic Communications for Contact Tracing Within Administrative Boundaries

3. The system of claim 1, wherein the first emitter device is among a plurality of standalone emitter devices of an administrative domain and each of the emitter devices broadcasts one or more acoustic tokens that each comprise a unique emitter device identification element associated with a corresponding one of the emitter devices.

4. The system of claim 1, wherein at least one of the first user device or the second user device performs decoding of the one or more acoustic tokens associated with the emitter device.

7. The system of claim 1, wherein each of the acoustic tokens associated with the emitter device comprises a static emitter identification element.

8. The system of claim 1, wherein each of the one or more acoustic tokens associated with the emitter device comprise a static emitter identification element and a pseudorandom time element.

9. The system of claim 8, wherein the pseudo-random time element associated with each of the acoustic tokens is based on a corresponding result from a deterministic random word generator associated with the emitter device.

10. The system of claim 1, wherein each of the one or more acoustic tokens associated with the emitter device comprises an ephemeral emitter identification element.

11. The system of claim 10, wherein verification of each ephemeral emitter identification element is performed for determining whether information associated with a corresponding acoustic token is trusted.

12. The system of claim 10, wherein the emitter device plays out one or more ordered sets of ephemeral emitter identification elements across a plurality of acoustic tokens broadcast in the acoustic volume.

13. The system of claim 12, wherein each of the ephemeral emitter identification elements in the one or more ordered sets of ephemeral emitter identification elements corresponds only to the emitter device in view of one or more other emitter devices in a same administrative domain as the emitter device.

15. The system of claim 1, wherein the information associated with the one or more acoustic tokens from the first user device is obtained based on a period of time associated with the disease.

16. The system of claim 1, wherein the information associated with the one or more acoustic tokens from the second user device is obtained based on a period of time associated with the disease.

17. The system of claim 1, wherein the determining that the first user was exposed to the disease is further based on information associated with radio frequency communication between the first user device and the second user device.
